After some recent research there's reason to believe there's less than 380cc's of meth currently being used. We're waiting to hear back from Coolingmist on this...
A little scary considering the power levels, but at the same time quite amazing given its been making 600+ for 2500 miles now.
Also amazing is the amount of potential still waiting to be extracted... More fuel, more meth, new manifolds, custom Eshaft and center plate. Then turn up the boost to match and 800 rwhp on pump almost seems too easy.


Sick numbers rx72c...

haven;t dyno'd with the meth yet as I just installed it saturday, but previous on pump gas was 383whp at 12psi w/ 11.4:1 afr
now on 15psi and a 12.1 afr dropping to 11.8. hoping to hit the dyno again after the holidays.
and that 383whp was on enzo's dyno dynamics setup.
going out on a dyno jet next time out will redyno old setup and new for comparison.

Why are you running such lean afrs?

Bring it into the low 11s at least.

Also. You should go back to dyno dynamics so you get back to back power reading change.

Dynojet is going to be completely different.

yeah I know, but I live almost 200 miles from enzo's shop. that's quite a drive. I'll do a base run on what I was tuned at with the meth off, then see where it goes from there.

hey guys i threw my car up on the dyno on thurs night, just a 13b mild port, scr seals, with a chinese GT45 (69mm comp wheel) also its through a big stall auto so that kills the power a bit, has RR water injection and crane CDI, lol it made 300.0rwkw on 19psi, i turned it up and it smashed the tires on the dyno, the operator was saying i was holding it flat too quickly or some ****.. broke a strap and got over it.

dunno if the dyno is SAE or if it has STD's , but it's a brand new twin inhibitor dyno dynamic's, i know there alot harsher than the one's you guy's have over there, by feel it has alot more power than the 350rwhp it had on a mainline dyno(even harsher) before.
